About Free VTT Dungeon Tiles
Free dungeon tile generator for VTT. Create Roll20, Foundry VTT, and Owlbear Rodeo battle map tiles — pixel or sketch, 13 themes, ZIP export, no sign-up.
How to use
- Pick a theme from the right panel — Dungeon Stone, Cave, Crypt, Sewer, Castle, Forest Ruins, Ice, Volcanic, Mansion, Library, Temple, Pirate Ship, or Alien/Void. Each theme ships a curated palette and mood that flows through every tile category.
- Browse the tile catalog tabs on the left: Floor (9), Wall (16 with auto-corner logic), Door, Trap, Furniture, Lighting, Stairs, Decor. Click any tile to render a live preview showing exactly how it looks at the chosen export size.
- Toggle the rendering mode between pixel art (sharp 32-px source) and sketch (hand-drawn 64-px source). Pixel suits classic top-down dungeon crawlers; sketch matches Pathfinder battle maps and old-school AD&D style hex maps.
- Adjust the detail slider — Minimal, Standard, or Ornate. Minimal works when you need clean tiles for crowded battle maps; Ornate adds rubble, cracks, and texture flourishes for centerpiece encounter tiles.
- Click Export PNG for a single tile at the chosen export size, ready to drop directly onto a Foundry VTT or Roll20 grid. The 140-pixel default matches the 5-foot D&D grid square that those VTTs use out of the box.
- Click Sprite Sheet to bundle the entire tile set (every variation in the active theme) into one PNG — useful for Tiled, GMS2, or any engine that consumes texture atlases. Each tile sits at a known offset for easy slicing.
- Click Save to My Assets to push the active tile or full set into your 3D Assets dashboard. Group dungeon themes into Collections (one per campaign) so you can pull a complete tile kit into a VTT scene with a few clicks.
Examples
Build a complete dungeon for Foundry VTT
Pick the Crypt theme, export every floor type, the full 16-piece wall set, doors, traps, and an altar at 140 pixels. Drop the sprite sheet into Foundry, configure the grid, and you have a complete tile kit for a haunted-tomb adventure module — every tile tonally consistent, no Photoshop required.
Stock a Roll20 modules library
Generate every theme (Dungeon, Cave, Crypt, Castle, etc.) at 140 pixels with Standard detail, save each as a Collection in My Assets, and you have a reusable library covering most adventure environments. Pull from the right Collection per session without the per-game hunt for matching art.
Frequently asked questions
Will these tiles snap to a Roll20 or Foundry VTT grid?
Yes — the default 140-pixel export size matches the 5-foot grid square that both Roll20 and Foundry VTT use as their canonical scale. Drop the PNG into a scene, set the grid to 140 pixels, and the tile aligns square-on-square. Owlbear Rodeo and Fantasy Grounds also accept PNG imports at any size, so you can scale the export up or down without quality loss because the source is procedurally rendered.
Can I use these in commercial published modules?
Yes. Tiles exported from Dungeon Tile Mixer are yours to publish — DriveThruRPG modules, Kickstarter campaigns, professional VTT bundles, printed adventure books. ToolFluency claims no rights to the output. The art is procedurally generated at export time so each PNG is unique to your settings; no third-party assets are embedded that would carry a license string into your finished product.
How does the wall auto-tile system work?
The 16-piece wall set covers every adjacency case a grid-based dungeon needs — pillar, four caps (N/E/S/W), straight horizontal and vertical, four corners (NE/SE/SW/NW), four T-junctions, and the cross. Most VTT and engine tile editors auto-pick the right wall piece based on neighbors. The naming convention matches Tiled and Godot Wang-tile expectations so engine import is one click.
What's the difference between pixel and sketch mode?
Pixel mode renders crisp 32-pixel-per-tile source art with hard edges — best for retro top-down RPGs, Game Boy aesthetic prototypes, or any tile that needs to read at a small zoom level. Sketch mode renders 64-pixel-per-tile pencil-style art with double-stroke lines and texture variation — best for Pathfinder battle maps, old-school AD&D hex maps, and printed atlas pages.
Can I export a complete dungeon tileset as one file?
Yes. Click Sprite Sheet and the tool packs every tile in the current theme (floors, all 16 walls, doors, traps, furniture, lighting, stairs, decor) into a single PNG atlas at known offsets. This is the format Tiled, GameMaker Studio 2, Godot's TileSet, and Phaser's tilemap loaders all consume natively. Slice on the 32 or 64 pixel boundary depending on your render mode.
Do exported tiles work for printed gameplay?
Yes. Choose Sketch mode and the 1024-pixel export to drop tiles into Affinity Publisher or InDesign for a printed dungeon book. The procedural ink stroke holds up at 300 DPI on letter or A3 paper. For tabletop minis on real grid mats, print at 1 inch per square (so each 5-foot tile lands at 1 inch) and your 25-mm minis sit perfectly inside each room.
